Barry (Customer) asked a question.
I'm trying to a Run Command from Cmore EA9 panel to GS4 drive. RS485
I'm using the protocol: "Automation Direct GS4 Drive Serial". I read that a 1 must be written to a 16 bit word for "RUN". All the buttons in Cmore are discretes; so, I can't select the tag. How do I write a "1" to the word for a Run Command? Or is another method better? Thanks
Hi Barry,
Try using the Event Manager Database.
The pushbutton will activate an internal Bit momentarily.
When the bit from the pushbutton turns on then move a value of 1 into the tag name.
I hope this helps you out.

You will also need to move a 0 to that location to stop the drive..
I am trying the event however I can't get the Bit State to highlight. My Run tag is 16 a bit integer. I have to delete what uses that tag to edit it and try another data type.
Hi Barry,
I am not following you. You will create an internal bit in the tag database that will indicate when the pushbutton is selected. (Momentary)
The tag database also has to have an External tag for the word parameter that you are changing.
I have attached a sample program showing the start and stop bits on a screen.
Let me know if you have any questions.

I have not found a data type for the tag that will let me select "Signed Integer" when picking the tag for the event. Also, the pushbutton data type is discrete; I must find a way to trigger the event with the discrete pushbutton. This seems cumbersome. Since DA drive have their own driver, I thought a Cmore panel could command the drive more directly.
Thank you Garry. I can't open it with my Cmore 6.53 but will try to figure it out.
I am using C-More version 6.70.

I have upgraded. When I try to run the drive using the start button on the EA9, I get an error "Error code 0x0003 returned from PLC". The drive is in remote. The only thing I see is in the event, my Pump Run CMD tag doesn't show the P9.27 detail.
Hi Barry,
Can you attach your C-More program?
You can try to change the type in your tag database to "BCD int 16".

There was a parameter in Digital that kept it from working. It now starts and stops from the panel. Thank you Garry!
